MP3 to WAV: What You Should Know
MP3 is a lossy, compressed format — useful for storage and streaming but not ideal for editing, since every re-save adds more compression artifacts. WAV is uncompressed PCM audio, the standard for DAWs like Audacity, Pro Tools, and Logic, and for burning audio CDs.
- Converting MP3 to WAV does not restore audio quality lost during the original MP3 compression — it only stops further loss from future edits.
- Expect the WAV file to be roughly 10x larger than the source MP3.
- Use this when a program or hardware device specifically requires WAV/PCM input rather than compressed audio.
